MatchCollection.Count Property

Gets the number of matches.

Namespace:  System.Text.RegularExpressions
Assembly:  System (in System.dll)

public int Count { get; }

Property Value

Type: System.Int32
The number of matches.

Implements

ICollection.Count

Accessing individual members of the MatchCollection object by retrieving the value of the collection's Count property causes the regular expression engine to populate the collection using direct evaluation. ln contrast, calling the GetEnumerator method (or using the foreach statement in C# and the For Each...Next statement in Visual Basic) causes the regular expression engine to populate the collection on an as needed basis using lazy evaluation. Direct evaluation can be a much more expensive method of building the collection than lazy evaluation.

The following example illustrates the use of this property.


// Report the number of matches found.
Console.WriteLine("{0} matches found in:\n   {1}", 
                  matches.Count, 
                  text);
